Will Atenton (Daniel Craig) quits a high-profile job in Manhattan to relocate his wife Libby (Rachel Weisz) and their two daughters to a quaint New England town. But, as they settle into their new life, they discover their perfect home was once the murder scene of a mother and her children. When Will investigates, he's not sure if he's seeing ghosts or if the tragic events are somehow related to his past. The only clues come from the mysterious neighbor Ann (Naomi Watts), who helps him piece together this haunting puzzle.
